Ai no Meikyu

Ai no Meikyu(愛の迷宮)

Miyamoto Maki plays Ayaka, the daughter of a distinguished family who winds up in a loveless marriage with Mitsuo ( Hosaka Naoki ), the heir of a business concern. After she discovers that he's having an affair with his brother's widow Kanako ( Takahashi Kaori ), she ends up falling for the servant Kota (Sakaki), who is also married. The complex web of love even extends to the characters' eventual children, who appear in the latter half of the series. -- Tokyograph (Source: Drama Wiki)
